6.5.4.9 Check shut off torque
Parameters:
SOTH
(Shut off torque high),
SOTL
(Shut off torque low)
Function:
The torque measured at the shut off point of the step is checked to be between the high
limit SOTH and the low limit SOTL.
Both limits are optional. Leaving them blank disables the check but the result value is still
calculated and reported.
This check requires that at least one sample is collected after the torque spike elimination
phase. If not, and at least one limit is specified, the steps status is set to
Fatal
and the error
bit of the respective limit is set.

Trace
:
TH and TL are shown in trace as horizontal lines from step start to step stop after post step
check time. The lines are only shown when Torque vs. Time is selected and Check limits
